Question

solve for x and graph the solution on the number line below. 9 < 7 + x answer attempt 1 out of 2 < > ≤ ≥ or inequality notation: number line: -12 -10 -8 -6 -4 -2 0 2 4 6 8 10 12

Explanation:

Step1: Isolate x

Subtract 7 from both sides of the inequality $9 < 7 + x$.
$9-7<7 + x-7$

Step2: Simplify

$2 < x$ or $x>2$

Answer:

Inequality Notation: $x > 2$
To graph on the number - line, draw an open circle at 2 (because 2 is not included in the solution set) and draw an arrow to the right to represent all numbers greater than 2.
